So 5 days ago my boyfriend of a little over a year broke up with me. When I would ask why he would always say that he just lost feelings for me. I asked if there was anything I could do and I told him that I knew we could fix it. We had already been through a lot together so I knew this could've been worked through together but he said he didn't want to work through it. I asked how this happened and he said he had been feeling this way for a few weeks. A few weeks before this he basically did the same thing saying he didn't know if he loved me anymore but we solved things and we were fine. But the first time he started to lose his feelings he was talking to this other girl which he thinks is a whore and knows his friend likes. Once we solved things the first time I told him I didn't want him to really be talking to her anymore so he stopped. Then he started talking to her again and all of a sudden he broke up with me. He always denies that this other girl had anything to do with it but I always think she does. If she doesn't actually have anything to do with it, is there any way I could get him back? And if so, how do I do that?
